In symmetric key encryption, only one key is used for encryption and decryption. The key used in this type of encryption is called a secret key. The secret key that the sender and receiver use could be a specific code or a random string of letters or numbers produced by a random number generator. Asymmetric encryption uses two separate keys: a public key and a private key. Often a public key is used to encrypt the data while a private key is required to decrypt the data. The private key is only given to users with authorized access. As a result, asymmetric encryption can be more effective, but it is also more costly.

Encryption in PHP is actually simple (we're going to use openssl_encrypt () and openssl_decrypt () once you have made some decisions about how to encrypt your information. Consult openssl_get_cipher_methods () for a list of the methods supported on your system. The best choice is AES in CTR mode:To encrypt a message M you use the formula C = M e mod n, where {e,n} is the public key of the receiver you want to send the message. To decrypt the message C, the receiver uses the formula M = C d mod n, where {d,n} is the private key of the receiver. Notice that from steps 1 to 6, you are just calculating the private and public keys.The data key is encrypted under a KMS key and stored in the metadata of the secret. To decrypt the secret, Secrets Manager first decrypts the encrypted data key using the KMS key in AWS KMS. Secrets Manager does not use the KMS key to encrypt the secret value directly. Instead, it uses the KMS key to generate and encrypt a 256-bit Advanced ...PS: Once you go with option 3 and random IV's - start looking into how you'll determine if decryption was successful.
